Nor should you.
That’s my experience as well. Sometimes certain items can spike on the Amarr market, because it can be tricky (for some people) to get stuff in there, but in general, price levels are where Jita’s at. Of course, if you’re looking for clothes or Officer modules, you better haul your butt over to Jita.
I’m actually surprised how Amarr is not much more expensive than Jita. I would have expected the opposite.
